Description

The present invention relates to the structure of a stepper, which is simple in structure and maintains a center of gravity balance.

In general, health equipment is intended to obtain the same health effect as outdoor exercise by exercising indoor exercise in a simulated manner indoors. As an example, a stepper (also called a stepper) performs a simulated walking by moving up and down with a footboard when the user steps on it.

The basic structure of the known stepper is almost the same, mainly the front end of both footboards are pivoted on the base, both footboards are connected to the chain (or wire) by a hydraulic cylinder, and both footboards are damped by the hydraulic cylinder's damping action Are moved up and down relative to each other, and a hydraulic cylinder gives resistance suitable for the movement of the footboard.

However, the above-described known stepper has a relatively high basic structure cost, and it is complicated to adjust the movement force of the hydraulic cylinder. High manufacturing costs directly affect market competition. Also, when the footboard is used, the higher the height when it is raised, the greater the angle of front tilt, so the center of gravity of the user is not stable and it is difficult to maintain equilibrium. It is dangerous to pay attention, limit activity, and possibly injure you.

The problems to be solved are that the manufacturing cost is high and that the center of gravity of the footboard is not stable, so that a relaxed exercise cannot be performed.

According to the present invention, a user puts his / her feet on a footboard assembly unit and uses the footsteps to make the both footboard assembly units move up and down. Among them, the front and rear movable rods are installed at the bottom of each footboard assembly unit, and the front and rear ends of the footboards are pivoted at the front and rear movable rod ends. The most important feature is that an interlocking part is installed between the two footboard assembly units, and when the two footboard assembly units move up and down, the footboard always keeps the horizontal state and the user can easily maintain the center of gravity.

The structure of the stepper of the present invention has an advantage that the structure is simple, the center of gravity is maintained, and the exercise can be enjoyed without worrying about the feet.

As shown in FIGS. 1 and 2, two sets of footboard assembly units 20 are installed on the base 10, and these two sets of footboard assembly units 20 are provided on both feet by means of both footboards 23 having a method of fixing the angle. It is something to step on and exercise.

Among them, each footboard assembly unit 20 has front and rear movable rods 21 and 22 pivoted on the base 10, and the ends of the front and rear movable rods 21 and 22 pivot with the front and rear ends of the footboard 23, respectively.
Further, an interlocking component 30 is installed between the two footboard assembly units 20, and the interlocking component 30 is pivotally mounted on the pivot shaft 41. Separately, the two linkages 32 are connected between the rear movable rods of the two footboard assembly units 20 and the interlocking parts 30, and the two footboard assembly units 20 are moved relative to each other by towing the linkages 32 and the interlocking parts 30 when the user steps. And move up and down.
These are shown in FIG.

During the movement of the both footboard assembly unit 20, the footboard 23 is always maintained in a horizontal state by the interlocking action of the front and rear movable rods 21 and 22, and the user can easily keep the center of gravity in equilibrium. Therefore, you can move both feet freely, and you can exercise without taking care of your feet. Further, a shock absorbing part 11 constituted by a compression spring is installed at the rear end position of the foot plate 23 of the both foot plate assembly unit 20 facing the base 10 so as to reduce the impact when the foot plate 23 descends.

As shown in FIG. 4, the pivot shaft 41 of the present invention is provided with upper and lower clamping pieces 42 and 43 at the upper and lower positions of the interlocking component 30, and the upper and lower clamping pieces 42 and 43 are arranged at the other end opposite to the pivot shaft 41. One screw rod 51 is installed. As for the interlocking part 30, when the resistance plate 31 extends to the periphery of the screw rod 51, and the interlocking part 30 swings to the left and right with the vertical movement of the two footboard assembly unit 20, the resistance plate 31 is located between the upper and lower clamping pieces 42, 43. To slide. Therefore, the gap between the upper and lower clamping pieces 42 and 43 is adjusted by the first screw rod 51, the sliding ability of the resistance plate 31 is changed, and the exercise force of the footboard assembly unit 20 is adjusted. A friction plate 55 in contact with the resistance plate 31 may be installed between the upper and lower clamping pieces 42 and 43, and is composed of rubber (or a similar material) between the first screw rod 51 and the upper clamping piece 42. The elastic packing 56 is installed, and a frictional resistance force suitable for the resistance plate 31 is formed by the action of the friction plate 55 and the elastic packing 56.

Further, the base 10 is provided with a base plate 54 at the rear end position of the pivot shaft 41, and a second screw rod 52 is screwed sideways on the base plate 54. The end of the second screw rod 52 is mutually pushed with the lower end of the pivot shaft 41, and the angle of the pivot shaft 41 is adjusted with the second screw rod 52, so that the relative position between the interlocking component 30 and the both footboard assembly units 20 is adjusted. The height of the footboard 23 is adjusted. The first screw rod 51 for adjusting the motive force and the second screw rod 52 for adjusting the altitude of the footboard 23 are provided with nuts 53, and the user manually rotates the first screw rod 51 and the second screw rod 52. To adjust the equipment.
